<h2>Answer:</h2>
Option: C is the correct answer.
C.) x = −3.8, 3
<h2>Step-by-step explanation:</h2>The function f(x) is given by:
and the function g(x) is given by:
Now, we are asked to find the solution of the equation:
i.e. we have to find the value of x such that both the functions are equal i.e.
Now, on solving the equation using the quadratic formula i.e. the solution of the equation:
is given by:
Here we have:
Hence, the solution is given by:
Consider expression First, you can factor it:
Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus, is always even.
